GOBN-SHELLER.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, OLoNzo R. DINSMOOR, of Chester, in the county of Rockingham and State of New Hampshire, have invented a new and useful Improvement in Harriss Corn-Shellers; and I do hereby declare that the following is a full and exact description of the construction and operation of the same.

The nature of my invention consists in making the cards or shelling plates of the sheller one concave and the other convex.

To enable others skill-ed in the art to make and use my invention I will proceed to describe its construction and operation.

In the accompanying drawin s, Figure 1 2 a vertical section through its length.

My machine consists of two platesset or cast with teeth and connected at one end by a pivot or hing-e, one of them to be provided with a handle at the end opposite the hinge by which it is to be rubbed across the surface of the other, which is previously screwed or otherwise made fast to some stationary body. An oblong form may be given to the plates A, and B, of about nine by fourteen inches, the lower one or bed plate 13, to be perforated with screw holes, one of which is shown at c, 0, by which it body. The upper one has a handle (Z, extending from one end, and both have at the opposite ends (which are to match) a projection e, c, of the same thickness as the plates. A hole f, is made through each of these projections vertically to receive a bolt 9, which forms the pivot or hinge of the 1,088, dated February 24, 1889.

plates. The hole in the upper plate is elongated to allow for its rise and fall on the bolt in themanner of a hinge, and the hole in the under plate is countersunk below rather more than half way through to receive a spiral spring k, shown in the sectional drawing, surrounding the bolt, constantly exerting a downward pressure, which tends to drawthe two plates together dur ing their operation and accommodates their distance to the size of the ear of corn between them. A small pin 2' passes horizontally through the projection of the upper plate and the bolt which secures them together. The inner surface of the two plates are concave and convex, matching each other, and this constitutes my improvement, the advantages of which are that in having the surfaces of the plates concave and convex the cob is bent and the corn opened, thereby rendering it much easier shelled. Also by bending the cob the tip end is brought in contact with the teeth of the convex plate, which shells it clean. The spring attached to the bolt adapts the machine to the shelling large or small ears of corn.

That I claim as my invention and desire to secure by Letters Patent is Making the shelling plates or cards concave and convex in the manner and for the purpose herein described and this I claim as an improvement on a patent previously granted.
